Summary: This study characterizes the biogeochemical properties of the Eastern North Pacific upper ocean during the Winter of 2013-2014 using observations and models, and finds that the Blob is associated with increased aragonite saturation and decreased oxygen concentration.

Summary: This study analyzes the persistent 2019-2020 marine heatwave and its climate effects, finding four sea surface temperature peaks in the Northeast Pacific, with different warm core structures at various depths. The two wintertime peaks are mainly influenced by surface heat flux anomalies, while the spring peak may be induced by a combination of heat flux and vertical mixing.

Summary: The Northeast Pacific "Blob" has a significant influence on the prediction of the Atlantic warm pool (AWP), with signals being transmitted through the seasonal footprint mechanism to trigger anomalous atmospheric pressure and subsequently cause an increase in AWP sea surface temperature. The North Pacific Blob can serve as an effective predictor for the AWP.

Summary: This study identifies four Blob events in the summer of 2014, 2015, 2019, and 2020 and demonstrates the diversity in the formation of summer Blob events. The weakened North Pacific subtropical high and spring sea surface temperature warm anomalies are the main drivers of Blob events. A regression model considering both factors successfully reproduces the observed Blob variation.

Summary: This study assesses the role of mixed layer depth (MLD) in the location and development of warm blobs in the Northeast Pacific. The research finds that warm blobs occur more frequently in areas with shallow MLD and are mainly confined to the mixed layer. Anomalous MLD and heat flux have a significant impact on the development of warm blobs.

Summary: Seagrass ecosystems are prevalent throughout Pacific Island Countries and Territories, with the highest diversity found in Melanesia and Papua New Guinea. While seagrass conservation has shown signs of improvement, it remains marginalized in marine conservation efforts, with traditional knowledge playing an increasingly important role in local resource management. The Pacific Islands stand out as a global bright spot for seagrass resilience, with relatively low pressures compared to other regions.

Summary: This study investigates the spatial distribution and diversity of phytoplankton in the North Pacific Subtropical Gyre and the California Current System. The results show distinct community compositions in these two ecosystems, indicating specific adaptations of phytoplankton to different trophic states. Coccolithophores and dinoflagellates dominate the North Pacific Subtropical Gyre, while diatoms and cryptophytes prevail in the California Current System. Chemotaxonomy combined with microscopy is an effective method for studying phytoplankton diversity.

Summary: The study on the effects of the Northeast Pacific marine heatwave of 2014-2016 on the Salish Sea estuarine waters revealed that while higher temperatures led to increased biological activity, it was primarily due to increased freshwater and nutrient loads rather than warming from the heatwave itself. Strong vertical circulation and mixing helped mitigate temperature increases, keeping the waters cooler relative to the continental shelf during the marine heatwave.

Summary: Warm blobs are persistent warm seawaters over the Northeast Pacific (NEP) that have significant impacts on marine ecosystems and climate. Recent warm blobs occurred consecutively in the spring and summer of 2021 and 2022, with different locations. Atmospheric processes played a positive and dominant role in the evolution of these warm blobs, but their contribution alone cannot sustain a season. The seasonal persistence is due to the offset between atmospheric and oceanic processes, highlighting the need for further investigation to enhance predictability.

Summary: Marine heatwaves are prolonged warm water events that are increasing in frequency and magnitude due to rising global temperatures. The Northeast Pacific Blob, an unusually widespread marine heatwave, affected ecosystems across the Northeast Pacific and was found to be influenced by both surface warming and northward advection of warm, salty water. Analysis of temperature and salinity data collected by northern elephant seals showed significant warm anomalies throughout the water column and peak warming in late 2015, contributing to our understanding of the thermal content and structure of the Blob.

Summary: Coral reef science aims to understand coral health and resilience to combat reef loss caused by environmental stress. The intricate symbiotic interactions within the coral holobiont play a vital role in coral resilience. The Tara Pacific project utilizes advanced sequencing technologies to study the biodiversity and complexity of coral holobionts across the Pacific Ocean, providing valuable insights for future investigations of coral reef dynamics and their future in the Anthropocene.

Summary: The biodiversity of glasswork wastelands is influenced by soil fertility and local-scale drivers, supporting a high level of biodiversity and providing wildlife sanctuaries for Orthoptera and diurnal Lepidoptera. These wastelands can also be utilized for phytoextraction of strategic metals in a circular economy model.

Summary: The shrinkage of glaciers and the development of post-glacial ecosystems due to anthropogenic climate change are rapidly occurring ecosystem shifts with significant ecological and societal consequences. However, there is no comprehensive spatial analysis to quantify or predict this important change. A study found that by 2100, the decline of glaciers outside of Antarctic and Greenland ice sheets could result in the emergence of new terrestrial, marine, and freshwater ecosystems spanning an area similar to that of Nepal or Finland. The future of glacierized areas highlights the importance of glaciers and emerging post-glacial ecosystems in the face of climate change, biodiversity loss, and freshwater scarcity.

Summary: The Tara Pacific expedition conducted a comprehensive study of coral ecosystems in the Pacific Ocean from 2016 to 2018. The expedition collected nearly 58,000 samples from 32 islands, including corals, fish, plankton, and seawater, for advanced analysis. The methodology of the sampling process is described, and the different datasets generated by the expedition are made accessible. The released datasets provide valuable environmental context data and have the potential to address various scientific questions.
